8.6. Cleaning the flue gas passes and the flue
tubes
Normally it is sufficient to clean the flue gas passes and
the flue tubes once a year. First pull the stove away from
the wall so as to create enough room to work at the
back.
To clean the flue gas passes, proceed as follows:
Disconnect the flue baffle from the guide by lifting it.
Draw the left cladding down out of the guide and place it
down in the ash space. Then the flue baffle can be
removed and the upper part of the combustion chamber
can be cleaned.
Then remove the right side wall. This is fixed with
connectors. Pull the side wall off sideways.
Undo the screws and remove both the covers of the
openings. Now you can clean the exposed insides of the
flue gas passes. (See Figure 8 a+b).

After completion of the cleaning make sure that
when putting back the covers, the seals are seated
in the right positions. It is essential to replace
defective seals.
8.7. Cleaning the induced draught housing and fan
This housing is made accessible for cleaning by undoing
the 4 nuts shown in Figure 9. (See arrows).
Remove the induced draught motor by pulling it out.
Now clean the flue gas passes, the induced draught fan
and the flue tubes with a brush and an ash vacuum
cleaner.
Then reassemble the components in reverse order.
Make sure that the seal is seated in the right position
again. It is essential to replace defective seals.
Make sure of the electrical connections on the fan motor
and their correct positions.

9. Description of the components
9.1. Storage container (pellet tank)
32 kg of wood pellets can be stored in the storage
container. This quantity permits constant operation for
up to 50 hours.
9.2. Screw conveyor motor / screw conveyor
The screw conveyor motor drives the screw conveyor.
This delivers the wood pellets from the storage container
to the combustion chamber (combustion pot). The screw
conveyor motor’s rotation speed is regulated and it
therefore delivers the required supply quantity to the
modular heat output (2.5 kW to 8 kW).
